WebA Turing machine is an abstract model that can simulate any computer algorithm. Input and output data is stored on the same linear storage, called a "tape", which is manipulated by the machine according to a set of predetermined rules. The tape moves through a "read/write head" that reads then writes one data unit at a time. WebA Turing Machine is a mathematical construct. For the purposes of mathematics, it's a set of rules that you follow. It doesn't get the "instructions" from anywhere, it's defined by the person designing the Turing Machine. A Turing Machine can read what is written where the "read head" is positioned. fly fisher olympia wa

WebA Turing machine is an idealised computing device consisting of a read/write head (or 'scanner') with a paper tape passing through it.
